Camphor: Uses and Risks

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Camphor, a white, crystalline substance with a strong odor, is widely used in various traditional and modern medicinal applications. It is known for its anti-inflammatory, analgesic, and antimicrobial properties. However, recent studies have highlighted potential risks associated with its use, particularly at higher doses. This article explores the uses and risks of camphor, drawing on findings from multiple research studies.

Uses of Camphor

Traditional and Modern Applications

Camphor has been traditionally used in the treatment of respiratory conditions such as coryza and bronchitis, as well as musculoskeletal pains and wounds2. In some cultures, it is also used in the preparation of local infusions for managing conditions like piles, back pain, and erectile dysfunction4. Additionally, camphor is sometimes added to poultry diets to improve reproductive functions5.

Anti-inflammatory and Antioxidant Properties

Camphor exhibits significant anti-inflammatory and antioxidant properties. It has been shown to reduce the gene expression of inflammatory markers such as TNF-α, NF-κB, and IL-6, and increase the expression of antioxidant enzymes like GPX and CAT6. These properties make camphor a potential candidate for mitigating conditions associated with oxidative stress and inflammation.

Risks of Camphor

Toxicity and Histopathological Changes

Despite its beneficial uses, camphor can induce toxicity and cause histopathological changes in various organs. Studies have reported oxidative stress and damage in the brain, lung, liver, kidney, and testes following camphor administration1. In female rats, camphor exposure led to vacuolation in hepatocytes, inflammatory cell infiltration, and loss of cellular architecture in the liver, as well as edematous glomeruli and congestion in the kidneys3.

Neurotoxicity

Camphor has been associated with neurotoxic effects, including seizure induction. It inhibits GABAergic neurotransmission, leading to oxidative and inflammatory damage in the brain. This results in neurodegenerative changes such as degenerated axonal and dendritic projections and neurofibrillary tangles2.

Hormonal Disruption

Camphor can disrupt hormonal balance, particularly affecting reproductive and thyroid hormones. In male rats, camphor administration significantly reduced levels of luteinizing hormone (LH), testosterone, and thyroid-stimulating hormone (TSH), while increasing free triiodothyronine (fT3) at certain doses4. In Japanese quail, camphor increased thyroxine (T4) and triiodothyronine (T3) levels, and improved libido and reproductive performance at specific concentrations5.

Reproductive Toxicity

Camphor has adverse effects on reproductive parameters. It significantly decreases sperm count, live and mature sperm proportions, and testicular morphometric parameters. However, the co-administration of vitamin E, an antioxidant, can moderate these toxic effects7.

Conclusion

While camphor has several beneficial uses, particularly in traditional medicine and as an anti-inflammatory and antioxidant agent, its potential risks cannot be overlooked. High doses of camphor can lead to significant toxicity, neurotoxic effects, hormonal disruption, and reproductive toxicity. Therefore, the use of camphor should be approached with caution, and further research is needed to fully understand its safety profile.
